A CNC screw machine produces small parts. Despite its name, the part need not necessarily be a screw. They can also produce things like nuts and bolts.
A recent search of eBay produced several results for CNC screw machines. The price for these machines ranged from $4,500 to over $15,000 depending no size and capacity.
Used CNC machines can be bought at specialized retailers. Most manufacturers of CNC machines also sell used machines. One can also check the Alibaba site, where lots of manufacturing equipment is sold.
Screw machines are used to make equipment that can be screwed but can also be used for other purposes. A mechanical screw machine is operated by cams while a CNC screw machine is computerized and does not require human intervention. A screw machine is a metalworking machine tool used in the high-volume manufacture of turned components. A CNC machine is computerized control, which means that once they are set up and started running, they continue running and producing parts with very little human intervention.
A lead screw is used to convert rotary motion into linear motion. It is commonly used in machinery where precise linear movement is required, such as in CNC machines, 3D printers, and automotive applications.
CNC stands for computer numerical control. CNC milling machines are used to cut parts with the same dimensions numerous times. These machines are more accurate and faster than manual cutting.

They are long srews that go through a fitting. They offer support. Some are made for CNC machines. You can read some more at http://www.techno-isel.com/Tic/LPBallScrew.htm A ball screw in usually made out of hardened steel. It used to make a very fine adjustment on the object that it supports.
A pipe threader is used to thread the inside of pipes with accessories such as a die head, either manually or with a machine. Die heads are usually used with lathes,turret lathes, CNC lathes, or screw machines.
CNC stands for computer numerical control. CNC milling machines are used to cut parts with the same dimensions numerous times. These machines are more accurate and faster than manual cutting.
It's a make of controllers and drives for CNC machines.
A CNC machinist is a skilled Machinist who specializes in computer-controlled machines (lathes, mills, etc.). Traditionally, CNC machinists started their training with "manual" machines, but today many CNC machinists quickly transfer to CNC machines and never truly learn manual machining.
The original mechanical screw machines, which automated the creation of small metal parts was created in the late 1800's. Computerized control, CNC, came in the 1950's, but it doesn't appear there is any record of the person or company who first combined the two technologies.
